The type of vitamin D that is best for an individual is contingent on their own needs. Vitamin D3, also called cholecalciferol, is the form most commonly found in foods and supplements. However, Vitamin D2, or ergocalciferol, is a form of vitamin D synthesized by plants.
Vitamin D2 is not as effective as Vitamin D3, but it is the form typically used in fortified foods and multivitamins.
For individuals who do not have an adequate source of vitamin D from diet or sun exposure, Vitamin D3 supplementation is likely the most beneficial choice. Vitamin D3 is efficiently converted into calcitriol, the active form of vitamin D, in the body.
Calcitriol is necessary for the body to absorb calcium, improve immune function, regulate metabolism, and more. Evidence shows that supplementing with Vitamin D3 helps raise blood levels of vitamin D more efficiently than D2 does.
Vitamin D3 is available in over-the-counter supplements, typically in a 400-800 IU dose. Individuals may require higher doses of vitamin D to achieve desirable blood levels; individuals should consult with their health care provider for specific recommendations.

Which vitamin D is better D or D3?
Vitamin D and Vitamin D3 are both forms of Vitamin D. Both forms have many benefits, including helping the body absorb calcium and phosphate, supporting a healthy immune system, and helping with cell growth.
Vitamin D is naturally synthesized in the body when the skin is exposed to sunlight. Vitamin D typically comes from fortified foods or supplements. Vitamin D3, also known as cholecalciferol, is a type of Vitamin D that is present in animal-based products such as eggs, fatty fish, and organ meats.
Vitamin D3 is also made in the body when the skin is exposed to ultraviolet rays from the sun.
When it comes to which type is better, the answer is up to you. Research suggests that both forms of Vitamin D may be beneficial and important for overall health. The Vitamin D Council recommends consuming Vitamin D3 supplements instead of Vitamin D2 as it has been found to be more effective at raising blood levels of Vitamin D.
Ultimately, the type of Vitamin D you choose most likely depends on personal preference and what is more accessible to you.
Should I take vitamin D or vitamin D3?
That depends on your individual needs and goals. Vitamin D and D3 are both forms of vitamin D and both are essential for health. Vitamin D is the general form and is found in animal sources like fatty fish and eggs, while vitamin D3 is the sun-activated form of vitamin D, found in fortified foods, supplements, and produced by the body when it’s exposed to the sun.
Both forms of vitamin D when consumed, are converted into a common form called 25-hydroxyvitamin D and stored in the liver, prior to being used by the body’s organs and tissues. Both are essential, but the benefits of one may be greater than the other, depending on your body’s needs.
For overall health, we recommend supplementing with both forms of vitamin D. However, if you have specific health goals related to vitamin D supplementation, such as strengthening bones, then vitamin D3 may be the better choice.
This is because vitamin D3 is more easily absorbable into the body than vitamin D. Additionally, there is evidence that suggests vitamin D3 may be more beneficial when it comes to boosting the immune system, while vitamin D may be better at helping lower blood pressure.
So before you decide on which form of vitamin D to take, consult with your health care provider to determine which type, and the specific amount, best suits your individual needs.
What is the difference between D vitamin D and vitamin D3?
Vitamin D is a fat-soluble vitamin that is produced by the body when exposed to sunlight and is essential for good health. There are two forms of vitamin D that can be found in nature – Vitamin D2 and Vitamin D3.
Vitamin D2 (ergocalciferol) is generally found in foods that are derived from plants or fungi, such as mushrooms, while Vitamin D3 (cholecalciferol) is found in foods derived from animals. Vitamin D2 is made from the ultraviolet (UV) light acting on substances contained in food.
Vitamin D3 is primarily made from the UV light acting on the cholesterol in the skin.
Both forms of vitamin D have similar functions, however vitamin D3 has more hormonal activity. Both D2 and D3 are able to bind to the vitamin D receptor, but D3 has approximately 3 times greater affinity for this receptor.
In addition, Vitamin D2 may be used in fortified foods, while vitamin D3 is generally used in dietary supplements. The Institute of Medicine recommends that infants, children, and adults should get 600 IU (15 mcg) of vitamin D3 daily.
Why do doctors prescribe vitamin D instead of D3?
Doctors prescribe vitamin D instead of D3 for a variety of reasons. Vitamin D3 is the form of vitamin D that is most commonly found in nature, while vitamin D2 is synthetic. Both forms of vitamin D are metabolized by the body in the same way and have similar effects when taken in the correct doses.
However, research indicates that vitamin D3 may be more effective in raising and maintaining blood levels of vitamin D and may also be better absorbed by the body.
The decision to prescribe one form of vitamin D over the other may depend on the individual’s specific needs or symptoms. Vitamin D3 may provide more health benefits than vitamin D2, especially in people with lower levels of vitamin D.
Others may prefer vitamin D2 since it is a synthetic substance, or because it is vegan-friendly. In addition, vitamin D2 may be less expensive than vitamin D3.
In the end, it is important to follow your doctor’s instructions and take the form of vitamin D they have prescribed. Both forms of vitamin D can be beneficial but depending on the person, one form may be more beneficial than the other.
Is there a downside to taking vitamin D3?
Yes, there is a downside to taking vitamin D3. Although vitamin D3 is important for bone health, it can reach toxic levels in your body if taken in excessive amounts. Signs and symptoms of too much vitamin D3 can include nausea, vomiting, weakness, increased thirst, increased urination, muscle pain, constipation, confusion and headache.
Taking excessively high amounts of vitamin D3 over an extended period of time can lead to an elevated calcium level, which can damage the kidneys and other organs. It is important to get your blood tested regularly if you decide to take vitamin D3, and consult with a doctor if you experience any of the above symptoms.
When should you not take vitamin D3?
You should not take Vitamin D3 if you’re taking medications that are affected by it, such as bisphosphonates, hormone replacement therapy, or antifungals. Additionally, too much Vitamin D3 could be toxic and cause nausea, vomiting, decreased appetite, abdominal pain, weakness, confusion, fatigue, headaches, and kidney stones.
People with certain medical conditions such as hypercalcemia, sarcoidosis, or Williams Syndrome should also not take Vitamin D3. Women who are pregnant or lactating should also not take Vitamin D3 without consulting with a doctor first, as it can potentially cause harm to the fetus or newborn.
Lastly, if you have allergies to Vitamin D3 itself or any of its components (such as soy or wheat), you should not take it.
Why would a doctor prescribe 50 000 units of vitamin D?
A doctor may prescribe 50,000 units of vitamin D for any number of reasons. Vitamin D is important for maintaining bone health, and supplementation is often recommended to help increase levels in cases of deficiency.
Vitamin D deficiencies are more common in individuals who have a limited sun exposure due to their location or lifestyle, or individuals who have fat malabsorption, or lack of vitamin D in their diets.
Low levels of vitamin D, can increase the risks for osteoporosis, fractures, falls, mental health problems and other conditions.
Taking 50,000 units of vitamin D is often prescribed as a way to quickly raise a person’s low vitamin D levels. It is typically the recommended dose for individuals who are deficient but not in the extremely low levels of deficiency.
A doctor will typically follow up the recommendation by having the patient’s vitamin D levels tested periodically to ensure they remain within a healthy range.
What are the signs you need vitamin D?
Vitamin D is essential for good health, as it helps regulate the amount of calcium and phosphate in the body, which are important for normal growth and development of bones, teeth, and muscles. Without enough vitamin D, an individual may experience a wide range of signs and symptoms, some of which can be more severe and potentially debilitating.
Common signs you may need vitamin D include:
– Bone and joint pain: A deficiency in vitamin D can lead to weaker bones, which can result in pain in areas where bones support and connect to other bones, such as in the hips and legs.
– Hair loss: Dry, brittle hair and large amounts of hair loss can be a sign of a vitamin D deficiency, as it helps your body absorb and store enough calcium for normal growth.
– Low energy: Vitamin D can also help regulate the metabolism, and necessary amounts are needed for normal and healthy levels of fatigue.
– Trouble sleeping: If you’re having trouble sleeping, low vitamin D levels can be the cause, as sun exposure is often used as a natural treatment for insomnia.
– Brittle nails: If you notice your nails have become brittle or cracked, this may be the result of inadequate levels of vitamin D, as it helps promote normal nail health and growth.
– Weak immune system: Vitamin D is also essential for maintaining a strong and healthy immune system, and a lack of it can lead to increased susceptibility to a variety of illnesses.
If you have any of these signs or symptoms, it’s important to speak with a doctor to get your levels checked. This can help to identify any deficiencies and plan for appropriate supplementation.
What is the most effective form of vitamin D3?
The most effective form of vitamin D3 for humans is cholecalciferol, which is the form synthetically made when exposed to ultraviolet light. Cholecalciferol is biologically active and readily absorbed into the blood from the intestine, unlike other forms of vitamin D.
Additionally, cholecalciferol is sometimes referred to as “sunshine in a bottle,” as it mimics the natural form of vitamin D developed in the skin when exposed to sunlight. It is possible to purchase cholecalciferol in the form of supplements such as tablets, capsules, syrups, solutions, and creams.
Regardless of the form of supplementation, vitamin D3 is the most potent form of vitamin D and known to have the highest bioavailability, meaning it can be more easily used in the body to help with a variety of health outcomes.
Is it better to take vitamin D2 or D3?
When it comes to choosing between vitamin D2 or D3, there is no right answer as to which is “better.” However, there are some advantages and disadvantages to consider when making the decision.
Vitamin D2, which is also known as “ergocalciferol,” is the synthetic, plant-based form of vitamin D. This form is typically taken as a supplement and is recommended by many health organizations, including the American Medical Association, as an adequate source of the vitamin.
Vitamin D2 is particularly beneficial because it is widely available, cost-effective, and easy to find.
Vitamin D3, or “cholecalciferol,” is the natural animal-based form of vitamin D. This form is generally found in foods such as egg yolks, fish, and animal fats. Vitamin D3 offers some advantages over D2 in that it is thought to be absorbed better in the body and is more easily retained.
In addition, some studies have suggested that Vitamin D3 may be more effective in maintaining healthy levels of vitamin D in the body than Vitamin D2.
Ultimately, the choice between Vitamin D2 or D3 should be guided by your individual needs and intended uses. If you’re taking a supplement to increase the level of vitamin D in your body, your doctor may recommend that you take D3 for its enhanced absorption capabilities.
However, if you’re looking for an inexpensive and widely available option, D2 may be a better choice. Ultimately, it is important to speak to your doctor to determine which form of vitamin D is best for your specific health needs.
Is vitamin D2 equivalent to vitamin D3?
No, vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol) are not equivalent. Vitamin D2 is made from the UV irradiation of ergosterol from the fungus ergot, while vitamin D3 is made from the UV irradiation of cholesterol from animal sources.
Although both vitamin D2 and D3 can be used to increase vitamin D levels, studies have shown that individuals with higher levels of vitamin D3 experience a more significant increase in serum 25-hydroxyvitamin D than those with higher vitamin D2 levels.
Furthermore, studies suggest that chronic consuming of vitamin D2 may even lead to decreased 25-hydroxyvitamin D levels, while vitamin D3 consumption resulted in a positive relationship with levels of serum 25-hydroxyvitamin D.
While both vitamins are essential to bodily functions, vitamin D3 is believed to be more efficiently absorbed, making it a better source of supplementation than vitamin D2.
Is D2 or D3 better for osteoporosis?
The answer to this question will ultimately depend upon the individual needs of the person with osteoporosis. Both Vitamin D2 and Vitamin D3 can help to strengthen and maintain bone health, however there are some differences between them.
Vitamin D2 generally comes from fortified foods and dietary supplements, while Vitamin D3 is naturally present in the body and comes from UVB-exposure from sunlight and certain foods like fatty fish.
Vitamin D3 is widely considered to be the more bioavailable form, meaning that it can be better absorbed by the body than Vitamin D2. It also has a longer half-life in the body, which can make it more effective in maintaining adequate concentrations over a longer period of time.
Ultimately, the best choice for a person with osteoporosis would be the one that best meets their individual needs. If they do not live in an area with adequate UVB exposure, they may want to consider taking a supplement with Vitamin D3.
If they already get adequate UVB exposure or live in a warm climate, then Vitamin D2 may be a better option. In all cases, it is important to speak to your doctor before taking any supplements.
What are the symptoms of vitamin D2 deficiency?
Vitamin D2 deficiency typically presents with a variety of symptoms including fatigue, skin rashes, depression, muscle weakness, bone and joint pain, impaired wound healing, and increased risk of infections such as colds, flu and other upper respiratory infections.
In addition, those who suffer from vitamin D2 deficiency may experience shortness of breath, low blood pressure, and digestive issues such as constipation. Osteoporosis, which is a weakening of the bones due to the lack of calcium, is another common symptom of vitamin D2 deficiency.
A symptom of vitamin D2 deficiency that is often overlooked is a low vitamin D level in the body. A deficiency in vitamin D2 can lead to a decrease in calcium absorption, which can lead to a decrease in the amount of calcium available in the body.
This can lead to weakened bones and increased risk of fractures. Therefore, it is important to get a full blood panel to test vitamin D2 levels in order to get proper treatment.
Does vitamin D2 give you more energy?
No, Vitamin D2 does not give you more energy. Vitamin D2 is a source of Vitamin D, which helps your body to absorb calcium, but it does not provide an energy boost. Vitamin D can be found in a few foods, such as fatty fish, egg yolks, and fortified milk and cereals, and it can be taken as a supplement.
Vitamin D plays an important role in regulating the levels of calcium and phosphorus in your body and in maintaining healthy bones and teeth, but it does not provide extra energy. To get an energy boost, you need to consume calories, which come from foods rich in carbohydrates, protein, and fat.
Additionally, exercise can help to increase your energy levels.
